Toward Methanol-Based Biomanufacturing: Emerging Strategies for Engineering Synthetic Methylotrophy in .

The global expansion of biomanufacturing is currently limited by the availability of sugar-based microbial feedstocks, which require farmland for cultivation and therefore cannot support large increases in production without impacting the human food supply. One-carbon feedstocks, such as methanol, present an enticing alternative to sugar because they can be produced independently of arable farmland from organic waste, atmospheric carbon dioxide, and hydrocarbons such as biomethane, natural gas, and coal. The development of efficient industrial microorganisms that can convert one-carbon feedstocks into valuable products is an ongoing challenge. This review discusses progress in the field of synthetic methylotrophy with a focus on how it pertains to the important industrial yeast, . Recent insights generated from engineering synthetic methylotrophic xylulose- and ribulose-monophosphate cycles, reductive glycine pathways, and adaptive laboratory evolution studies are critically assessed to generate novel strategies for the future engineering of methylotrophy in .
